Análise de política monetária sobre a arrecadação do ICMS do Estado do Ceará utilizando o modelo de vetores autorregressivos

Abstract

This research aims to analyze quantitatively the impact of monetary policy promoted by the Central Bank of Brazil on the behavior of the tax revenue of ICMS in Ceará. Thus, we considered information on the collection of industrial, retail and electric, beyond the rate of open unemployment in Fortaleza, and how the transmission mechanism of monetary policy used the Selic interest rate. The model used here is composed of vector autoregression and arguments based on Toda and Yamamoto (1995), and impulse response functions and variance decomposition. The results suggest that a positive shock in monetary policy has negative impact on the tax revenue of ICMS of industry and trade, while the effect on revenues in the electricity sector is positive. And the positive impact of interest rate on the unemployment rate in Ceará is positive, so increases in interest rates tends to increase unemployment in Ceará.
